Semiconductor Devices: MOSFETs

[@0451Deus]

Some of the best videos on electronic devices on CZcams. Thanks Prof. Fiore!

One question when V-GS is positive then there will be a I-GS current flowing through the n-channel??

[@spurti]

Or is it zero??

[@ElectronicswithProfessorFiore]

@@spurti MOSFETs don't have a junction so there is nothing to be forward biased, hence gate current is tiny, even with a positive Vgs (for N channel).

@@ElectronicswithProfessorFiore Ohh so we can neglect I-GS and it is essentially zero
